Yup, Dodge uses NGK as stock plugs. The manual said every 30k miles on my Nitro. The plugs barely made it to 25k miles. City miles worn them down good. So I started to change them at 25k miles. My old Ram was the same way. 25k mile new plug maintenance. The X5 will get a new set again at 175k miles. 25k mile replacement is good maintenance. Easier on the coils tool.
